Taking antipyretic drugs basically does not cause diarrhea, but often causes sweating all over the body, because patients taking antipyretic drugs will lower their body heat through sweating, which means that the patient’s body temperature returns to the normal range. If a patient has diarrhea after taking antipyretic medication, it may be an adverse reaction to the medication. It is also possible that the patient has a gastrointestinal disorder, such as an intestinal infection, and therefore may experience diarrhea. If the diarrhea is relatively mild, it can be temporarily observed and treated with probiotics if necessary, and most of them can be cured soon. If it is a more serious diarrhea symptom, the patient needs to go to the hospital and cooperate with the doctor for examination and treatment in time.
